 ed marine mammal”\n\n\n\nSpeaker: Dr. Carolina Bonin Lewallen\, Marine and
  Environmental Science Department\, Hampton University\n\n\n\nDr. Carolina
  Bonin earned her doctoral degree in Marine Biology from the Scripps Insti
 tution of Oceanography\, University of California San Diego. During her Ph
 D she employed neutral molecular markers in population genetics and geneti
 c pedigree reconstruction studies of Antarctic fur seals in the wild. Dr. 
 Bonin’s interest in acquiring genomic analysis skills led her to transitio
 n into a post-doctoral position in biomedical sciences at the Mayo Clinic 
 Rochester MN. While there\, she worked on mining patient epigenomic data\,
  in particular DNA methylation\, to search for genes associated with osteo
 arthritis. At Hampton University\, Dr. Bonin is developing a new research 
 agenda on the identification of molecular bio-indicators\, particularly mi
 croRNAs\, for marine organism health.\n\n\n\nAbstract: The field of conser
 vation genetics has traditionally focused on the study of the mechanisms t
 hat generate and maintain genetic diversity. Severely depleted populations
  are often the focus of scientific studies. Thus\, conservation efforts ty
 pically only happen after an irreversible loss of diversity has already oc
 curred over many generations\, which is sometimes immeasurable. However\, 
 what can we learn from organisms and/or populations that have recovered fr
 om demographic decline without significant loss of genetic diversity? In t
 he face of climate change\, can we use disturbance-resistant populations t
 o model and predict adaptive responses in other populations and species? A
 ntarctic fur seals recently recovered from local extirpation due to intens
 ive hunting in the early 19th century\, yet they maintain mysteriously hig
 h levels of genetic diversity. My research revealed\, contrary to historic
 al records\, that recovering populations likely received immigrants from m
 ultiple sources during the re-colonization process\, including remote refu
 gia where relict populations survived the sealing era. In addition\, my wo
 rk highlighted that although fur seals are highly polygynous (dominant mal
 es father most offspring) and present high levels of site fidelity (return
 ing to same breeding site year after year)\, levels of remating between ma
 les and females is very low. Importantly\, this indicated that behavioral 
 complexities can counter-act mate fidelity rates among individuals. This w
 ork highlights the importance of isolated populations\, which can harbor u
 nexpectedly high levels of genetic diversity.\n\n\n\nHost: Dr. J. Sook Chu
